Lesson 1 — Placing Our Local Landmarks on a Timeline

Summary

Learners build a timeline — a line that orders events from the past toward today — and place three or four local landmarks on it in order. The new skill this year is the why: learners name the clue (evidence) that tells them the order is correct — an old photo, an elder’s memory, a dated plaque, a story. This is the first real historian’s question at Grade 3: not just what came first, but how do we know?

Objectives

• Place local events or landmarks on a timeline in order and explain how they know the order is correct. (D08.S1.03.01)

Connection

You already know a day has an order — wake, eat, play, rest — and that a timeline lines up bigger events from before today. Your town or village has its own order of landmarks: a tree someone planted, a bridge that was built, a school that opened. Each one carries a clue about when it happened — a photo, a date carved on a plaque, a grandparent’s memory. Placing them in order and naming the clue is how people begin to tell the true story of a place.

Materials

• A long timeline strip (one per learner)
• A set of “local landmarks” cards for the worked example, each with a clue card
• Pencils and crayons

Preparation

• Draw or gather simple landmark cards: a young tree being planted, a bridge being built, a school opening. Give each a clue card: an old photo (the tree was small and new), an elder’s memory (“I remember crossing the river on a boat before the bridge”), a dated plaque (“School, built 1987”).
• Give each learner a timeline strip with a “long ago” end and a “now” end.
• Decide whether the line reads left-to-right or top-to-bottom, and keep it the same for everyone.

Facilitator note

This lesson is written to the learner (“you”). Ordering is a foundational skill, so teach it with a worked example first (Kirschner, Sweller & Clark, 2006): model placing three landmarks on the line, and for each one say the clue — “the photo shows the tree when it was small, so the tree was planted first; the plaque says the school was built in 1987, so it came later.” Then guide the same two moves for a second set before learners work independently. The evidence is the point of this grade: Grade 2 ordered events; Grade 3 adds “how do you know?” — a photo, a date, a memory, a building style. Keep landmarks local, real, and gentle (a tree, a bridge, a school, a market, a well), never frightening or private. Honor every body and every family shape: a learner who is blind or has low vision sequences real objects by touch and says or signs the order and the clue; a learner who does not use a speaking voice points or acts. Every place’s order of landmarks is real and worthy — a town, a village, a farm, or a settlement all have their own. Remember that different peoples mark time in different ways (many calendars, many ways of naming years) — a timeline is one tool among many, not the only truth about time.

Procedure

1. Gather and remember (5 min). Think of one thing in your town or village that has been there a long time, and one thing that is newer. Which came first? How do you know?
2. Meet the timeline and the clue (10 min). Look at the worked example: a line with a “long ago” end and a “now” end. Three landmarks — a tree planted, a bridge built, a school opened. For each one, name its clue: the old photo shows the tree when it was small; the elder remembers crossing by boat before the bridge; the plaque reads “built 1987.”
3. Guided practice (10 min). Mix the cards. Together, put them back in order, and for each say the clue that proves it: “The tree came first because… the school came after the bridge because…”
4. Build your own timeline (15 min). Choose three or four real landmarks from your place. Draw or show each one on its spot along your line, from “long ago” to “now,” and write or draw the clue that tells you the order.
5. Explain your order and your clue (5 min). Point to each landmark and say, “This came first because…” and “I know because…” You may point, act, draw, or sign.
6. Close (5 min). You just did what historians do: you ordered landmarks and explained how you know. A timeline with evidence is a true story of time.

Differentiation

• Support: Use only three landmarks, and place them together with clear gestures toward each clue.
• Support (blind/low-vision): Sequence real objects by touch and say or sign the order and the clue aloud; a partner reads the labels.
• Support (non-speaking): Order picture cards or objects and point to the clue cards instead of speaking.
• Support (Deaf/HH): The cards are already pictures — read the order with your eyes and hands, and sign “before,” “after,” and “clue” as you place each card.
• Support (motor-difference): Use a large, stable line and bigger cards; point or eye-gaze to each spot while a partner moves the card.
• Extension: Add a fifth landmark and name two different kinds of clue (a memory and a date), and tell which is more trustworthy for that landmark and why.

Assessment

• Formative (observation): Can the learner place three or four local landmarks on the timeline in a sensible order, from furthest back to most recent?
• Formative (oral/performance): Does the learner name a clue (photo, memory, date, story) that shows how they know the order — by speaking, signing, pointing, or acting?

Home connection

At home, ask someone to tell you about two or three landmarks in your place and how they know which is older — a photo, a memory, a date. Put them in order together and say the clue for each.

• Britannica Dictionary, “landmark” — defines a landmark as an object or structure on land that is easy to see and recognize (and, historically, a building or place that was important in the past), supporting the idea of local landmarks as markers in a place’s story. https://www.britannica.com/dictionary/landmark
